Ordered and delivered. HMC5843 3-axis magnetometer arrived. I'll be working on it shortly.
Will there be a USB connector on the upcoming Version 4 board? And do you have a link to the discussion area? I'll also be getting airspeed and pressure/temperature boards for this soon. Current platform 98" wing span MQ-9 Predator. Flight results will be logged and I hope to make that available here.
Greatly appreciate all the work you and your team does - A Mighty Thanks,
Hi Bill, just want to ask you, if the UAVdev board can send/receive data from Ground station Planner - Michael Oborne or even from happyKilmore´s ground station ?
thanks in advance.
Both the ArduStation and HappyKilmore's ground station will display data sent from the UDB to the ground station.
We plan to eventually support Mavlink in both directions when the UDB4 goes into production in a couple of months.
I need some help, I want to know if there is a way to see the coding structure flow diagram or some information as to how the code was set up. I want to attach a pressure sensor to the UAV V3 because I want to improve the accuracy of the altitude readings because we are flying closer to the ground possibly less then 60m. The problem is I dont know how or what to change to use the pressure sensor reading for the altitude measurements rather than the GPS. Is this a big job and would it possible with the new code and UDB 3?
@Tony, EM406A is the tried and tested GPS solution with uav devboard. It is the founder's (Bill Premerlani's) favourite. You don't need fast GPS with uavdevboard, as it works out where it is 40 times / second with the accelerometers and gyros. You just need an accurate position every second or so, and that is what matters. Even the delay (about 1.25 seconds) of the position does not matter, as the firmware takes that into account when updating the error in positioning by the accelerometers and gyros (integrations).
The MediaTek is still a very newly supported device for th UAV DevBoard. A lot of people reported problems, although they may have been running theUDB with the wrong clock rate. I recommend you search the uav devboard discussionlist. Best wishes, Pete
Thanks for the info, Pete. Wish I had read just a little further before ordering. :(
OK, I corrected my error, and ordered a 406A. On the gentleNav page, under "Optional Equipment", OpenLog is recommended as a data logger. Would there be any advantage to having the hard-wired OpenLog data recorder over using a stand-alone recorder? I already have a Canmore GPS logger that I use on my planes at times.
Yes, it is advantageous to connect the OpenLog data recorder.
The openlog will store the telemetry as it is emitted from the uavdevboard. The preferred format at the moment is SERIAL_UDB_EXTRA, and provides much more information than just the GPS data from the plane. You can see a copy of the telemetry format here. The additional information stored is:-
All of the above can be processed by the python script call flight analyzer. That will conver the data into a form that can be viewed either in a spreadsheet or in Google Earth.
The Google Earth representation puts the data into a time animated form, and colour codes all the waypoints as well as providing layers which allow the user to switch on:-
Best wishes, Pete
Thanks for that info, Pete. That kind of data will be very useful in my project.
Doing a bit of reading in the UDB instructions last night. After installing the Pic drivers, it said to power up UDB before plugging the programmer into UDB. I thought I had read somewhere that UDB can get its power from the PicKit USB connection. I'm still searching the forums and wiki, but Is there a preferred method?
